On-Site Waste Water Management

With over 20 years’ experience we specialise in:

• • Wastewater Management Reports: Single lots, Subdivisions, and Commercial Developments

• • Change in Residence/Dwelling Reports: (Additional Bedrooms, added dwellings or Granny flats)

• • Designs to meet WaterNSW NorBE requirements

• • Audits of existing systems for status and compliance

• • Expert witness for LEC and peer review

• • Designs for environmentally sensitive / constrained sites

• • Preliminary site investigation and options reports

• • Solutions for environmentally sensitive and unique locations

• • Viral die-off modelling

• • All treatment and disposal systems, including septic tank & trench, AWTS & irrigation and Wisconsin Sand Mounds.

• • Reports for pumpout where on site wastewater management is not an option

To get a quote:

So we can provide a quote, it would be helpful if you could email any relevant information, including:

1. Floor plans and site plans
2. Other development that is not shown on plans, such as sheds, pools, secondary dwellings and driveways.
3. Other relevant reports such as biodiversity/ecologist reports, flood studies etc
4. Relevant council correspondence if instructed to upgrade or replace a failing OSSM
5. Existing wastewater report for existing OSSM
6. Contour survey (as DWG if available)
7. What is the available water supply, ie town, tank only, or bore for potable use.
8. Name of applicant to be shown on report, or project manager if preferred.
9. Preferred method of wastewater treatment and disposal.
10. Preferred location of wastewater treatment system and disposal area.

Once the quote has been accepted:

1. After we are commissioned to do the report, we will need to undertake the soil and site assessment. This includes the geotechnical soil assessment of the preferred Effluent Management Area. This assessment examines soil physical characteristics and samples are taken away for other tests as required.
2. After our desktop and site assessment, we will send you preliminary site plans that show the size and location for wastewater disposal, with due consideration of your requirements and the assessment guidelines we must follow to obtain Council approval on your behalf.
3. On your acceptance, we will then prepare the final report. The whole process should take 10-15 working days to complete after we are commissioned.
4. You will need to provide Council with the specifications of the proposed treatment system and Section 68 application form. The manufacturer can provide this information, or you can find this on the NSW Health website.

Our commercial wastewater management projects include domestic and non-domestic wastewater management. Domestic includes childcare centres and schools, function centres and tourist developments. Non-domestic includes mushroom farms, intensive horticulture, poultry farms, dog boarding kennels, wineries, micro breweries & cideries and intensive equine developments. These assessments are subject to additional assessment criteria, soil testing and design work. The domestic wastewater management systems often require installation of commercial treatment systems (Sewage Management Facility) where wastewater strength and volume exceeds the capacity of larger domestic systems (AWTS). Non-domestic wastewater management systems can also use commercially available treatment systems, but are more often designs that that are tailored to suit the specific pollutants of concern.
